A framework Query Shuffler and Interaction aware query scheduler for workload management is introduced by Mumtaz Ahmad et al. Requests are given by the users in the form of queries and classified according to their type. All the queries are arranged using the Linear Programming and Non-preemptive shortest remaining time first. The work is implemented in IBM DB2 and evaluated via TPC-H benchmark. In Query Shuffler large jobs have to wait for long time even they have higher priority. Moreover, the average execution time is larger due to use of non-preemptive approach. |
